First of all, I am quite touched by your post. There are not many people who stop and really consider that their native religion might touch their families in the ways that Buddhism touched their children later in life.
I'm a firm believer that you can find kindness and love for the welfare of others no matter what religion you may have grown up with.
Every religion has at its core humans, and humans have some values I think that are supra-religion. The "ultimate" truths are the same for everyone.
Love thy neighbor as thyself
Do unto others as you would have done unto you
you know the usual ... don't be a piece of crap human being.
People are people, imperfect but always trying to do their best with what awareness they've got. That's just the brass tacks truth.
I come from mixed ethnicity as you already well know, so my perspective was always "in between" two worlds. I never felt I fully belonged to either, but I'm deeply grateful for all I've learned.
I have a good friend who is very very Christian. He's not preachy, he's not ignorant, he's a very well educated scientist, who also happens to endorse the philanthropic humanitarian values of Christianity and well, a feeling that god permeates all.
I have a deep amount of respect for those who use their native religion to do good. I do not believe all truth lies in one religion, because all truth lies in the human heart and that goes beyond aesthetic, usually makes the format of religion obsolete, when we connect at the basic level, my breath and heartbeat, your breath and heartbeat.
Aesthetic is simply a means to express the inherent resonance to truth. Like, you get what you give. That's a pretty old truth. Whether it's god giving it to you, or yourself, the truth stands, you get what you give, you get out of your experience what you bring with you into it every moment. This truth comes in every format, from heaven to hell, to this very moment, pick and choose.
I agree with HHDL that people should not be so ready to abandon their native religions, that is find what works for you, but honor where you came from whether you agree or disagree with the ideology, it's important to recognize the universality of human truth.
If you reach out to starving child, with a bit of food, no matter what religion you or he is, what faith you or he hold, that food helps his little belly. That is also part of the human heart.
I've been very wounded by institutions because they tend to distort and politicize the human truths, but if you can step a bit outside that, and just see the heart of the message, and encourage your interfaith dialogue by encouraging the human aspect of their practice, I think interfaith dialogue is not only possible, but connective.
If I were you, I'd apologize to your mother for being an a$$ with lots of ((hugs)) and recognize you came from her.
You may not be her, but you came from her and her kindness and unconditional caring for you in part made you who you are. No matter how silly her ideologies may have seemed to you in your life, there is no reason to be harsh with her, your mother. Yes the institution has many faults, and I'm sure you recognize that difference, a bright young man like you. You already know she is doing her best, and I'm sure you love her dearly, and part of you feels bad for having been hurtful to her at times. We all learn when we leave space for our loved ones to breathe and go at their own pace.
I have no relationship to my mother, and despite the heartbreak we've both experienced in our relationship, I'm grateful to her nonetheless for having tried her best with what she had to work with. Right or wrong, clumsy or skillful, she always tried to do "the right thing." And I'm sure your mother did too. All moms do. As guided or misguided as they may be as human beings, they love their children and try.
I feel that to honor our own imperfections and give ourselves the same gentleness in space to develop our own steps for our journey, we have to lend lots of room to other people and whatever faiths they hold, because they are humans before followers of this or that faith.
Does that make sense? Sorry for the long rant. BTW, I'm still subscribed to your blog and have been quite a long time, it's very nice to see you again.
I love you when you bow in your mosque, kneel in your temple, pray in your church. For you and I are sons of one religion, and it is the spirit. ---Kahlil Gibran
My addition is we are all of one religion - the human heart.
